Reporting on your Ultra Low Emission Zone

Caroline Russell: When will you update the initial one-month report on effects of the Ultra Low Emission Zone with the data after six months and one year?

The Mayor: I have published a report on the first four months of operation of the ULEZ, which showed that there was a large reduction in the number of older, more polluting, non-compliant vehicles: 12,500 fewer on an average day, a reduction of over a third, compared to March 2019. Later in the Autumn, once six months of data are available there will be another update. This will be further updated in Spring 2020 when 12 months of data is available.
